Alma 30-31,

“Have you read the Book of Mormon? Have you put to the test the promise found in Moroni 10:4, asking your Heavenly Father ‘with a sincere heart, with real intent, having faith in Christ’ whether or not that which is found in that book is truth?

“Many of you probably already know that the Book of Mormon is true, that Joseph Smith is indeed a prophet, and that this is the true Church of Jesus Christ. Some of you, however, may still be living on the testimony of others—your parents, your friends, your Church leaders. May I suggest that you set aside time every day to find out for yourself if the Book of Mormon is a true book, for it will change your heart and change your life. If you seek this knowledge ‘with a sincere heart, with real intent, having faith in Christ’ (Moroni 10:4), I promise that you will receive an answer. And once you know that the Book of Mormon is true, then it will follow that Joseph Smith is a prophet of God. You will have that burning testimony and knowledge that this church is true.

“Such knowledge, such a personal testimony, is essential if we are to safely navigate the sometimes treacherous paths through life with the adversary attempting to deceive us at every turn. As you keep the flame of testimony burning brightly, you will become a beacon of righteousness—even a light—for all to see. Said the Savior: ‘Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven'” (Matthew 5:16).
